Prevent dangling GetAttribute calls (#18754)
It appears possible that there could be a hang due to unread data from the
repo-attribute command pipes. This PR simply closes these during the defer.

Propagate context and ensure git commands run in request context (#17868)
This PR continues the work in #17125 by progressively ensuring that git
commands run within the request context.

This now means that the if there is a git repo already open in the context it will be used instead of reopening it.

Add warning for BIDI characters in page renders and in diffs (#17562)
Fix #17514

Given the comments I've adjusted this somewhat. The numbers of characters detected are increased and include things like the use of U+300 to make à instead of à and non-breaking spaces.

There is a button which can be used to escape the content to show it.

Make Requests Processes and create process hierarchy. Associate OpenRepository with context. (#17125)
This PR registers requests with the process manager and manages hierarchy within the processes.

Git repos are then associated with a context, (usually the request's context) - with sub commands using this context as their base context.

Enable show more files in diff for git <2.31 (#17733)
Unfortunately due to a misread on my behalf I missed that git diff only learned
--skip-to in version 2.31.0. Thus this functionality was not working on older versions
of git.

This PR adds a handler that simply allows for us to skip reading the diffs until
we find the correct file to skip to.

Use git attributes to determine generated and vendored status for language stats and diffs (#16773)
Replaces #16262
Replaces #16250
Replaces #14833

This PR first implements a `git check-attr` pipe reader - using `git check-attr --stdin -z --cached` - taking account of the change in the output format in git 1.8.5 and creates a helper function to read a tree into a temporary index file for that pipe reader.

It then wires this in to the language stats helper and into the git diff generation.

Files which are marked generated will be folded by default.

Prevent NPE in CommentMustAsDiff if no hunk header (#15199)
I do not understand how this can happen or why.

There is an apparent possibility for a comment.Patch to be missing a hunk header
- this should not happen and do not understand how. But it appears to happen on
1.13 at least in some case.

This PR will simply add a new section if the cursection is empty
thus preventing the NPE.

Fix broken spans in diffs (#14678)
Gitea runs diff on highlighted code fragment for each line in order to provide
code highlight diffs. Unfortunately this diff algorithm is not aware that span tags
and entities are atomic and cannot be split.

The current fixup code makes some attempt to fix these broken tags however, it cannot
handle situations where a tag is split over multiple blocks.

This PR provides a more algorithmic fixup mechanism whereby spans and entities are
completely coalesced into their respective blocks.

This may result in a incompletely reduced diff but - it will definitely prevent the
broken entities and spans that are currently possible.

As a result of this fixup several inconsistencies were discovered in our testcases
and these were also fixed.

#12771 attempted to fix diff by avoiding the git diff line as
it is possible to have an ambiguous line here.

#12254 attempted to fix diff by assuming that names would quoted
if they needed to be and if one was quoted then both would be.

Both of these were wrong.

I have now discovered `--src-prefix` and `--dst-prefix` which
means that we can set this in such a way to force the git diff
to always be unambiguous.

Therefore this PR rollsback most of the changes in #12771 and
uses these options to fix this.

Improved diff syntax highlighting fix (#12455)
Make previous fix from #12238 more robust since I saw a case where a diff changes only a single character in a chroma class instead of the entire thing. Add another more complicated test to match.

Fix Syntax highlight for token change in added/deleted code (#12238)
* Fix Syntax highlight for token change in added/deleted code

For diffs we first syntax highlight the before and after line then use a 3rd party diff library to find the difference in them and create a substring based on that, which we then highlight a 2nd time to show the specific difference within a line that has changed. In a specific case if the diffrence also changes the chroma class it will split in the middle of the attr and cause broken HTML:

```
<span class="nx">oldtext<span>
<span class="k">var newtext<span>
```

Will then split on

```
<span class="
```

Where the difference starts, and produce something broken like:

```
<span class="<span class="removed-code">nx"oldtext</span></span

```

Fix that by detecting when it happens and putting the HTML back together properly before highlighting the added/deleted code.

Fixes #12235

* fix lint

* apply fix to all diff sections. Also handle case where insert/remove starts with a closing span

* Add a test for this new code

* remove comment

Ensure syntax highlighting is the same inside diffs (#12205)
Make sure to end up with the same syntax highlighting inside various sections of diffs by processing the code first before detecting specific changes between the lines. Also try and make sure that when highlighting individual lines in a diff that it is tokenized the same as it would be when part of an entire file with more context.

Fixes: #12190

Make copy/paste work for source code (#12191)
* Make copy/paste work for source code

Fix regression casued by #12047 so copy/paste works properly in all browsers.

Fixes #12184

Also while looking at this I saw a small display issue for blame view. I think #12023 was merged into original PR through an update branch before #12047 was merged and made one of the css ruules not apply anymore.

* use pseudo-element to prevent copying of comment + symbol even when not visually selected

* remove added newline here should not be necessary anymore

* make sure empty line is newline so there is something to select and copy
